Title (EN) MULTI-BAND PLANAR INVERTED-F (PIFA) ANTENNAS AND SYSTEMS WITH IMPROVED ISOLATION
(FR) ANTENNES QUART D'ONDE COURT-CIRCUITÉES PLANES MULTIBANDES (ANTENNES PIFA), ET SYSTÈMES À ISOLEMENT AMÉLIORÉ
Abstract: front page image
(EN)Exemplary embodiments are provided of multi-band Planar Inverted-F antennas and antenna systems including the same. In an exemplary embodiment, a Planar Inverted-F antenna (PIFA) generally includes a planar radiator having a slot and a lower surface spaced apart from the upper radiating patch element. First and second shorting elements electrically connect the planar radiator to the lower surface. The PIFA also includes a feeding element electrically connected between the upper radiating patch element and the lower surface. The PIFA may be mounted on a ground plane that is larger than the lower surface of the PIFA.
(FR)Des modes de réalisation de la présente invention donnés à titre d'exemple concernent des antennes quart d'onde court-circuitées planes multibandes (antennes PIFA), ainsi que des systèmes d'antenne comprenant ces antennes PIFA. Dans un mode de réalisation donné à titre d'exemple, une antenne PIFA comprend généralement un radiateur plan comportant une fente et une surface inférieure séparée de l'élément de raccordement rayonnant supérieur. Un premier et un second élément de court-circuit connectent électriquement le radiateur plan à la surface inférieure. L'antenne PIFA comprend également un élément d'alimentation connecté électriquement entre l'élément de raccordement rayonnant supérieur et la surface inférieure. L'antenne PIFA peut être montée sur un plan de sol plus grand que la surface inférieure de l'antenne PIFA.
